Will this cheap thermal printer (model JP QR204) work same as this printer on arduino? Can I connect TX RX to arduino? Will this library work??

What important information did we get from your e-bay link?

● Beautiful appearance with mini shape, practical and convenient

Not exactly useful information.

While I agree with @PaulS my guess is that an Arduino could communicate with the printer. If the printer uses RS232 signal levels you will need a Max232 chip to convert to TTL signal levels as RS232 signals will probably damage an Arduino.

Whether the two printers respond to the same instructions is another matter entirely. You will need the datasheets for the printers to check that out.
